An automotive reciprocating engine design is disclosed preferably including an extruded cylinder bore block with cylinder bores and a surrounding coolant passage extending from a top flat surface to a bottom flat surface; a cast, closed bottom, open top crankcase with vertical walls having flat uppe

An automotive reciprocating engine design is disclosed preferably including an extruded cylinder bore block with cylinder bores and a surrounding coolant passage extending from a top flat surface to a bottom flat surface; a cast, closed bottom, open top crankcase with vertical walls having flat upper surfaces; and a stamped metal mid-plate interposed in sealing relationship between the bottom surface of the cylinder block and the flat top surfaces of the crankcase. The crankcase contains bearing supports for a crankshaft and the mid-plate contains holes for connecting rods attached to pistons in the cylinder bores. The design facilitates low cost manufacture of strong, light weight components and easier assembly of the engine, and permits flexible manufacture of a family of engines with different displacements by substitution of a cylinder block of different length or of different bore diameter.

The socket connector as claimed in claim 1, wherein the rear base forms a pair of posts at the mounting surface. 4. The socket connector as claimed in claim 1, wherein the at least one resilient contact has a tail portion extending out of the mounting surface of the housing. 5. The socket connector as claimed in claim 1, wherein the base portion forms a clip inclinedly extending beyond the mating surface of the housing, and a grounding plate extending beyond the bottom surface of the mating portion. movably assembled on the base for receiving the chip and comprises a slot (514) in alignment with the recess. The protector is placed upon the chip and comprises a number of legs (71) extendingdownwardly for pressing against the chip and a rib (72) projecting downwardly from a bottom face thereof for heightening the protector with respect to the chip. The actuating tool is inserted into the recess through the slot and drives the cover, the chipand the protector to move with respect to the base, thereby achieving an electrical connection between the chip and the socket.
